Answer:
PQ = 1/2BC
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
Because if you do 15•8•8 then it equals 960 and the formula for volume is l•w•h
-2+4 is 2/2 is (1,y)
4+0 divided by 2 is 2
coordinate is (1,2)
Question:
What is the common denominator of in the complex fraction
A)
B)
C)
D)
Answer:
Option D : 3 is the common denominator
Explanation:
It is given that the complex fraction
We need to determine the common denominator of from the complex fraction.
Let us consider the fraction
To find the common denominator, let us take LCM.
Thus, rewriting the above fraction as,
The LCM can be determined by multiplying the denominators.
Thus, we get,
Thus, the common denominator is 3.
Hence, Option D is the correct answer.
For Part A, what to do first is to equate the given equation to zero in order to find your x intercepts (zeroes)
0=-250n^2+3,250n-9,000 after factoring out, we get
-250(n-4)(n-9) and these are your zero values.
For Part B, you need to square the function from the general equation Ax^2+Bx+C=0. So to do that, we use the equated form of the equation 0=-250n^2+3,250n-9,000 and in order to have a positive value of 250n^2, we divide both sides by -1
250n^2-3,250n+9,000=0
to simplify, we divide it by 250 to get n^2-13n+36=0 or n^2-13n = -36 (this form is easier in order to complete the square, ax^2+bx=c)
in squaring, we need to apply <span><span><span>(<span>b/2</span>)^2 to both sides where our b is -13 so,
(-13/2)^2 is 169/4
so the equation now becomes n^2-13n+169/4 = 25/4 or to simplify, we apply the concept of a perfect square binomial, so the equation turns out like this
(n-13/2)^2 = 25/4 then to find the value of n, we apply the square root to both sides to obtain n-13/2 = 5/2 and n is 9. This gives us the confirmation from Part A.
For Part C, since the function is a binomial so the graph is a parabola. The axis of symmetry would be x=5.
